The STA5630 is a fully integrated RF front-end with a low noise amplifier (LNA) for low power GPS applications. It operates on a 1.8V supply voltage and is compliant with GPS and Galileo standards. The chip uses CMOS 65nm technology and features a 3-bit A/D converter and serial interface. It is suitable for automotive, cellular, and consumer battery powered applications.
The STA5630 is a fully integrated RF front-end designed to down-convert the GPS L1 signal from 1575.42 MHz to 4.092 MHz. It utilizes CMOS 65 nm technology and features an embedded high-performance Low Noise Amplifier (LNA) to minimize external component count. The device includes a 3-bit ADC that converts the Intermediate Frequency (IF) signal into Sign and Magnitude bits, which are used to control variable gain amplifiers.
